Dielectric Absorber Foam

ARC Technologies, a Hexcel company, offers a wide variety of RF absorbers. The lossy flexible foam (LS) product is a flexible, low density, high loss, carbon impregnated open cell foam.

Multilayer (ML) is a family of lightweight, flexible open cell foam absorption material, designed for broadband applications. 

The Lossy Rigid Foam (Rigid LS) product is an RF absorber ideal for machined cuts. With its low density, high loss, carbon impregnated open cell foam; it is available in a range of thicknesses with various carbon loadings. 

By closely controlling the dielectric properties, maximum absorption can be attained at specific frequencies. The ARC-SS series, (also known as Salisbury Screen), is based on the quarter wavelength absorption principle.

This microwave absorber can be die or laser cut to the desired sizes and configurations. It can be supplied in various thickness and combinations of materials to provide extended broadband capabilities.

The Reticulated Foam (RT) series is a group of open-cell, carbon-loaded foam absorbers. Exacting control of the conductive gradient provides outstanding broadband performance.
